WebSystems of high complexity involving reversible isomerization, decomposition and thermal and chemical activation can be considered. The density and sum of states are calculated … In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C4H9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n-butane can connect in two ways, giving rise to two "-butyl" groups: If it connects at one of the two terminal … See more According to IUPAC nomenclature, "isobutyl", "sec-butyl", and "tert-butyl" used to be allowed retained names. The latest guidance changed that: only tert-butyl is kept as preferred prefix, all other butyl-names are removed. … See more The four isomers (ignoring stereoisomers) of "butyl acetate" demonstrate these four isomeric configurations. Here, the acetate radical appears in each of the positions where the "R" symbol is used in the chart above: sec-Butyl acetate is … See more The tert-butyl substituent is very bulky and is used in chemistry for kinetic stabilization, as are other bulky groups such as the related See more Alkyl radicals are often considered as a series, a progression sequenced by the number of carbon atoms involved.

Or you can replace an H on C-2 with OH, and get 2-methyl-2-propanol (“t-butanol”). Those are the only two ways to do it! This applies to other groups too. So if we used Cl instead of OH, we’d have n-butyl chloride, s -butyl ...
